"The undersigned medical professional organizations are writing to express our significant concern regarding your recent action to terminate the entirety of the membership of the Advisory Committee on Immunization Practices (ACIP) within the Centers for Disease Control and Prevention (CDC). ACIP has, for decades, been a trusted advisory to CDC and the U.S. Department of Health and Human Services leadership, providing evidence-based recommendations regarding vaccinations through a transparent public process. We strongly urge you to immediately reinstate the terminated members of ACIP and honor their commitments to serve through the end of their appointed terms. When the terms of current ACIP members come to an end, we strongly urge you to follow the long-established public process for ACIP nominations and selection of members, ensuring that experience and subject-matter expertise are prioritized."
